Usage
Spelling tips for Christmas The word Christmas is hard to spell for two reasons. The letters ch- often make a [ ch ] sound, but in Christmas they represent a [ k ] sound. Also, there is only one s at the end, even though mass is typically spelled with a double s. As a final note, Christmas is a proper noun, and therefore the first letter is always capitalized. How to spell Christmas: Christmas is a celebration of the birth of Christ (also known as Jesus). Christ was a humble man, so he only needs one s at the end of his birthday (-mas).
